O2 Czech Republic

Operating within a highly competitive, saturated telecommunications market, O2 Czech Republic stands out by combining the most affordable fixed internet services, a superior mobile network, and exclusive television content. While mobile telecommunications services are its main revenue stream, O2’s fixed internet covers 99% of the country’s inhabited territory, positioning it as the largest internet provider for both businesses and households. O2 is also one of the country’s biggest providers of hosting, cloud services, managed services, and ICT.

Developing and offering pioneering telecommunications services such as cybersecurity and financial services, including device insurance and mobile travel insurance, is a hallmark of O2’s approach. Virtual operators also offer their services via the O2 mobile network.

In collaboration with Air Bank, the world of Unity benefits has opened up to hundreds of thousands of O2 and Air Bank customers. Unity offers a wide range of discounted devices and competitions for tickets to cultural and social events. The most popular reward, cashback, remains the privilege of joint O2 and Air Bank customers.

Oneplay, a partnership between O2 TV and CME’s Voyo streaming platform introduced in March 2025, is the next step in the evolution of O2 TV. It unifies streaming and live television into a single, user-friendly service with a broader content library and enhanced features. 

O2’s  long-term commitment to technological development and innovation has driven the ongoing expansion of its 5G network. In 2025, another major technological milestone was passed when O2 became the first operator in the Czech Republic to deploy a modern, 5G Stand­alone core (5G SA) in its network. This will give customers an advanced 5G+ network with a more secure, faster, and more stable connection. The new core runs in the cloud, operates independently, and is not dependent on 4G infrastructure. 

Customer security in cyberspace remains a priority for O2. In 2025, it deployed an anti-spoofing solution, initially within O2’s own network and subsequently in cooperation with other operators. This solution allows O2 to identify attempts to call customers using spoofed numbers and to block such calls before they reach the recipient. Over the past year, O2 blocked approximately 7 million such calls.

Artificial intelligence has become an integral part of O2’s operations. The company has focused on making AI systematically available across the organisation, allowing employees to work safely with modern AI tools. O2 has continued to develop its virtual assistants, including Eva and the internal Virtual Buddy tool. Artificial intelligence has also become a core element of the new Moje O2 app, which is gradually evolving into a fully self-service digital hub offering personalised content.

In this area, O2 relies primarily on its own in-house capabilities, which have been developed over more than a decade within its own AI competence centre, Dataclair.ai. This approach supports the responsible and secure development of artificial intelligence, underpinned by a long-term perspective. O2 is also active in the development of smart city infrastructure and solutions for future autonomous mobility.
